Jaguar Land Rover will be further expanding its powertrain line-up, benefiting both current and future models from both marques. At the centre of the expansion plan is the Ingenium four-cylinder petrol engine, which, in various states, will offer up to 25% more power compared to the engines they replace, and improvements in fuel consumption of up to 15%.

The new Ingenium petrol range (Ingenium diesel was launched last year) – described as the most advanced engines the company has ever developed – features technologies such as electrohydraulic valvetrain, integrated exhaust manifolds, and a twin-scroll turbocharger with ceramic ball bearings.

For maximum flexibility and scalability, a common architecture displacing 500cc of capacity per cylinder is employed. It will be used in applications as diverse as sports saloons and luxury SUVs. Production has started in the UK.

In addition to the new engine range, JLR has a £30 million transmission research project in place. Dubbed Transcend, it’s an eight-speed dual-clutch automatic setup which integrates low-range gear ratios as well as hybrid drive technologies. Weighing 20 kg less than an equivalent eight-speed automatic, Transcend is for longitudinal rear-wheel drive and all-wheel drive layouts.

With it, the efficiency of future vehicles will be improved and their all-wheel drive capabilities expanded, JLR says, adding that the gearbox has an ultra-wide ratio spread of 20, more than double that of conventional eight-speed automatics. This one is for the future.

“Environmental innovation is at the heart of our strategy to dramatically reduce emissions up to 2020 and beyond. With the Ingenium family of powertrains and advanced research projects such as Transcend, future Jaguar Land Rover vehicles will emit significantly less CO2. By 2020, new technologies will help us reduce our CO2 emissions by a further 25%,” said Nick Rogers, executive director of product engineering.
